This is a book of essays, written by H bomb survivors and concerned citizens.
It is a very useful book for anyone wanting to hear about the first use of the nukiller bomb, and about what nuclear weapons actually do to people.
It also contains messages of support from various foreign leaders, which include several presidents and prime ministers.
Unfortunately, this also includes a message from the still controversial ex-UN Secretary-General, Kurt Waldheim. Perhaps something could be done about that if a fourth edition were to be printed.
Aside from that, it is a very useful reference book.
